Description

Technical Field

[0001] This application relates to the technical field of dredging devices, and in particular to a municipal water supply and drainage dredging device. Background Art

[0002] In urban infrastructure construction, the municipal water supply and drainage system is a key facility for ensuring urban water supply and sewage discharge. Its normal operation is crucial for urban residents' lives and ecological environment maintenance. With the increase of service time, silt will continuously accumulate in the water supply and drainage system. If not cleaned in time, it is extremely easy to cause pipeline blockage, seriously weakening the drainage and water storage capacity of the system, and even may cause problems such as urban waterlogging and sewage overflow.

[0003] To solve the dredging problem of the municipal water supply and drainage system, related technologies have been constantly innovated. For example, the municipal water supply and drainage dredging device proposed in the Chinese patent with the publication number "CN222456339U" realizes dredging of pipelines with different diameters to a certain extent through structural designs such as an adjustment component, a driving wheel, a driving mechanism, a cleaning brush, a cutter head, and a dredging drill bit, alleviating the problem of insufficient applicability of traditional dredging devices.

[0004] However, this existing technology still has significant defects. It relies on multiple cylinders, motors, and electric telescopic rods to realize the telescopic adjustment of the cleaning brush plate and the driving wheel to adapt to pipelines with different diameters. This not only greatly increases the manufacturing cost of the equipment, but also, due to the large number of electronic devices, faces a high short-circuit risk in the high-humidity dredging operation environment. Once a short-circuit fault occurs, it is difficult to remove the dredging device from the pipeline, and it may even exacerbate the pipeline blockage, bringing great potential hazards to the subsequent normal operation and maintenance of the municipal water supply and drainage system. Therefore, it is urgent to develop a municipal water supply and drainage dredging device with lower cost, higher reliability, and adaptability to complex environments to overcome the deficiencies of the existing technology and ensure the efficient and stable operation of the municipal water supply and drainage system.

Detailed implementation manners

[0019] The following will further describe the present application in detail with reference to the attached Figure 1-8 drawings.

[0020] An embodiment of the present application discloses a municipal water supply and drainage dredging device. As Figure 1-8 shown, it includes a base 1. A moving mechanism 2 is fixedly installed on the top of the base 1. A frame 3 is fixedly installed on the top of the base 1. A top plate 4 is fixedly installed on the top of the frame 3. An inner box 5 is fixedly installed on the bottom of the top plate 4. A remote control module and a power supply module are arranged inside the inner box 5. A cleaning mechanism 6 is fixedly installed on the top of the top plate 4; The moving mechanism 2 includes a driving group 21, an adjusting group 22 and a moving group 23. The driving group 21 is fixedly connected to the middle of the top of the base 1. The adjusting group 22 is installed on the outer side of the top of the base 1 at equal intervals in a ring shape. The moving group 23 is fixedly connected to the outer side of the top of the adjusting group 22. When the municipal water supply and drainage dredging device operates, each component cooperates to achieve the dredging function. The base 1 serves as a basic support structure, carrying components such as the moving mechanism 2 and the frame 3. The remote control module and the power supply module in the inner box 5 provide guarantees for the remote control and power supply of the device. In the moving mechanism 2, the driving group 21 is located in the middle of the top of the base 1 and serves as the power core. After the first motor 214 inside it starts, through the meshing transmission of the inner bevel gear 215 and the outer bevel gear 213, the power is transmitted to the adjusting group 22. The adjusting group 22 is installed around the outer side of the top of the base 1 at equal intervals. The lead screw 223 inside it rotates under the action of power, driving the slider 222 to slide in the chute 221, and then driving the components of the moving group 23 connected to the slider 222. The moving group 23 is fixed to the outer side of the top of the adjusting group 22. When the adjusting group 22 drives it to extend outwards, the moving track 234 can fit the inner wall of the pipeline. At this time, using the operation of the track, the frictional force between it and the inner wall of the pipeline enables the device to move stably in the pipeline; by controlling the power output of the driving group 21, the telescopic amount of the moving group 23 can be accurately adjusted, so as to adapt to pipelines of different diameters and achieve flexible movement and diameter adaptation.

[0021] Please refer to Figures 1-6, the driving group 21 includes a trough body 211 and a mounting frame 212. The trough body 211 is arranged in a regular hexagon shape. Each inner surface of the trough body 211 is rotatably connected with an external bevel gear 213. The mounting frame 212 is fixedly connected to the middle of the top of the base 1. A first motor 214 is fixedly connected to the top of the mounting frame 212. The output end of the first motor 214 penetrates through the mounting frame 212 and is fixedly connected with an internal bevel gear 215. The internal bevel gear 215 is meshed and connected with each external bevel gear 213. The outer side of the external bevel gear 213 is connected to the inner side of the adjustment group 22. The adjustment group 22 includes a chute 221. The chutes 221 are arranged in an equidistant circular array on the top of the base 1. A slider 222 is slidably connected inside the chute 221. A lead screw 223 is rotatably connected inside the chute 221. The lead screw 223 is threadedly connected with the slider 222. The inner end of the lead screw 223 is fixedly connected to the outer side of the external bevel gear 213. The moving group 23 includes a fixing plate 231. The fixing plate 231 is fixedly connected to the top of the slider 222. A vertical plate 232 is fixedly installed at the outer end of the top of the fixing plate 231. A base frame 233 is fixedly installed at the upper end of the outer side of the vertical plate 232. A moving track 234 is rotatably connected inside the base frame 233. The base frame 233 is movably connected inside the frame 3. When this municipal water supply and drainage dredging device operates, the driving group 21, the adjustment group 22 and the moving group 23 cooperate with each other to realize the movement of the device and the adaptation to the pipe diameter. In the driving group 21, each inner surface of the trough body 211 arranged in a regular hexagon shape is rotatably connected with an external bevel gear 213. After the first motor 214 installed on the mounting frame 212 in the middle of the top of the base 1 is started, its output end drives the internal bevel gear 215 to rotate. Since the internal bevel gear 215 is meshed with each external bevel gear 213, the rotation of the internal bevel gear 215 can synchronously drive multiple external bevel gears 213 to rotate. The external bevel gear 213 is connected to the lead screw 223 of the adjustment group 22, driving the lead screw 223 to rotate. Through screw thread transmission, the slider 222 inside the chute 221 generates a linear sliding. The fixing plate 231, the vertical plate 232 and the base frame 233 on the top of the slider 222 are linked in sequence, pushing the base frame 233 of the moving group 23 to move inside the frame 3, and then driving the moving track 234 rotatably connected inside to extend outwards or contract inwards. When the moving track 234 extends to fit the inner wall of the pipeline, drive the moving track 234 to operate, and the device can move forward in the pipeline relying on the friction between the track and the inner wall of the pipeline; by controlling the operation of the first motor 214, adjusting the rotation direction and number of turns of the lead screw 223, accurately adjusting the displacement of the slider 222, so as to flexibly adjust the telescopic amount of the moving track 234 to adapt to municipal water supply and drainage pipelines with different diameters.

[0022] Please refer to Figures 1-4 and Figures 7-8, the cleaning mechanism 6 includes a second motor 61. The second motor 61 is fixedly connected to the top of the top plate 4. The output end of the second motor 61 is fixedly installed with a mounting group 62. The cleaning groups 63 are arranged in an equidistant annular pattern on the outside of the mounting group 62. The outside of the mounting group 62 is fixedly connected with a limiting group 64. The mounting group 62 includes a base block 621. The base block 621 is fixedly installed at the top output end of the second motor 61. A mounting seat 622 is fixedly installed on the top of the base block 621. Mounting grooves 623 are equidistantly arranged on the outside of the mounting seat 622. Mounting blocks 624 are inserted into the internal of the mounting grooves 623. The outside of the mounting block 624 is connected to the inside of the cleaning group 63. The top view shapes of the mounting block 624 and the mounting groove 623 are both set as convex shapes. The cleaning group 63 includes a rail frame 631. The rail frame 631 is fixedly installed on the outside of the mounting block 624. A return spring 632 is fixedly connected inside the rail frame 631. The outer end of the return spring 632 is fixedly connected with a movable plate 633. The outer end of the movable plate 633 penetrates through the rail frame 631 and is fixedly connected with a brush plate 634. A centrifugal weight ball 635 is fixedly connected to the side of the movable plate 633 located outside the rail frame 631. A connecting plate 636 is fixedly connected to the side of the movable plate 633 located outside the rail frame 631 and away from the centrifugal weight ball 635. A shovel plate 637 is fixedly installed at the outer end of the connecting plate 636. The cross-sectional shape of the end of the shovel plate 637 is triangular. During the use of this device, when the second motor 61 of the cleaning mechanism 6 is started, the output end of the motor drives the base block 621 to rotate, and the base block 621 then drives the mounting seat 622 to rotate. Since the mounting groove 623 on the outside of the mounting seat 622 cooperates with the convex-shaped mounting block 624, the rotation of the mounting seat 622 can synchronously drive the mounting block 624 and the connected cleaning group 63 to rotate around the central axis. In the cleaning group 63, the rail frame 631 rotates together with the mounting block 624. When the rail frame 631 rotates at a high speed, the centrifugal weight ball 635 at the outer end of the movable plate 633 has a movement tendency away from the center of rotation due to the centrifugal force. By continuously operating the second motor 61, when the centrifugal force is greater than the elastic force of the return spring 632, it overcomes the spring resistance and drives the movable plate 633 to move outward, so that the brush plate 634 and the shovel plate 637 extend out. At this time, the triangular cross-sectional shovel plate 637 can effectively cut and remove stubborn stains and garbage on the inner wall of the pipeline with its sharp end during the rotation;When the shovel plate 637 finishes removing the stains, the brush plate 634 closely adheres to the inner wall of the pipeline, and uses its special material to brush and clean the remaining flexible stains. When the second motor 61 stops running, the movable plate 633 that loses the centrifugal force drives the brush plate 634 and the shovel plate 637 to retract and reset automatically under the elastic restoring force of the return spring 632, which is convenient for the next cleaning operation. At the same time, the convex design of the installation block 624 and the installation groove 623 facilitates the disassembly and installation of the cleaning group 63, and is convenient for maintaining and replacing the worn shovel plate 637, brush plate 634 and other components. The shovel plate 637 is relatively sharp, and when it adheres to stubborn stains, it can further overcome the elastic force of the return spring 632 and can stably clean the inside of the pipeline.

[0023] Please refer to Figures 7-8The limiting group 64 includes a slot 641 and a limiting hole 642. The limiting holes 642 are arranged in a ring shape at equal intervals and are opened on the upper end of the outer surface of the mounting seat 622. The slot 641 is opened in the middle of the top of the mounting seat 622. An insert block 643 is inserted into the slot 641. The top of the insert block 643 is fixedly connected to the limiting cover 644. The outer side of the limiting cover 644 is fixedly connected with a positioning plate 645 at equal intervals. The outer end of the positioning plate 645 is threadedly connected to the limiting screw 646. The limiting screw 646 is set as a hand-tightening screw. The end of the limiting screw 646 is inserted into the limiting hole The top of the limit cover 644 is fixedly connected to the inside of 642, and the spiral reamer 647 is set in a conical shape. During the use of the device, the limit group 64 realizes the stable limit and convenient maintenance of the cleaning group 63 through the cooperation of various components. When installing the cleaning group 63, the mounting block 624 is inserted into the mounting groove 623 on the outside of the mounting seat 622, and then the insert block 643 is inserted into the slot 641 in the middle of the top of the mounting seat 622, so that the limit cover 644 covers the top of the mounting seat 622. At this time, the positioning plate 643 on the outside of the limit cover 644 is 45 is aligned with the outer surface of the mounting seat 622, and the hand-tightened limiting screw 646 is rotated to insert its end into the limiting holes 642 arranged in an annular shape at equal intervals on the upper end of the outer surface of the mounting seat 622, forming a mechanical limiting structure, which firmly fixes the limiting cover 644 and the mounting seat 622, thereby playing a stable limiting role for the cleaning group 63 installed on the mounting seat 622, preventing the cleaning group 63 from loosening or shifting during high-speed rotation. During the cleaning operation, the conical spiral reamer 647 fixed on the top of the limiting cover 644 rotates with the mounting seat 622, and its The spiral structure generates axial thrust when rotating, which can push the silt, debris, etc. in the pipeline to the rear of the device, and work together with the shovel plate 637 and brush plate 634 of the cleaning group 63 to further improve the dredging effect. When the cleaning group 63 or the spiral reamer 647 needs to be maintained or replaced, it is only necessary to rotate the limit screw 646 in the opposite direction to disengage it from the limit hole 642, and then the limit cover 644 can be easily removed, and the plug block 643 can be pulled out of the slot 641, and then the mounting block 624 and the connected cleaning group 63 can be disassembled, so as to realize quick disassembly and maintenance, and the operation is convenient and efficient.

[0024] The implementation principle of a municipal water supply and drainage dredging device in an embodiment of this application is as follows: The moving mechanism 2 of this device constructs a systematic in-pipe movement and pipe diameter adaptation system. When operating in a sewer pipe, the operator starts the first motor 214, and the motor output shaft drives the internal bevel gear 215 to rotate in a circle. The internal bevel gear 215 meshes with the external bevel gear 213 to form a stable transmission relationship, effectively transmitting the power to the lead screw 223 in the chute 221. Since the lead screw 223 adopts a standard screw drive design, during rotation, it can convert the rotational motion into a linear motion, thereby driving the slider 222 to slide along the track inside the chute 221. Thanks to the synchronous transmission characteristics of the internal and external bevel gears 213, a single first motor 214 can achieve the coordinated movement of all sliders 222; The sliding of the slider 222 drives the fixed plate 231 on the top of the sliding plate to generate a horizontal displacement. The fixed plate 231 sequentially pushes the vertical plate 232 and the base frame 233 to move outward through a rigid connection structure. During this process, the base frame 233 drives the moving track 234 to extend outward until the moving track 234 is in close contact with the inner wall of the pipe. When the appropriate contact pressure is reached between the moving track 234 and the inner wall of the pipe, the drive system of the moving track 234 is started, and the frictional force generated between the track and the inner wall of the pipe can provide a stable driving force for the device, enabling the device to move steadily in the pipe and achieve flexible position adjustment. At the same time, by precisely controlling the forward and reverse rotation and speed of the first motor 214, the moving track 234 can be accurately driven to perform telescopic actions on the frame 3. Whether it is a small-diameter pipe or a large-diameter pipe, this device can quickly adapt to different pipe diameter sizes by adjusting the telescopic amount of the moving track 234. This design that relies on a single power source to complete the telescopic control of the moving track 234 simplifies the power transmission structure of the device, reduces the equipment failure points, and significantly improves the adaptability, operation convenience, and operation stability of the device; The cleaning mechanism 6, as the core component for the device to achieve the pipe dredging function, provides a complete and efficient dredging solution. When the moving mechanism 2 drives the device to move in the pipe, the operator starts the second motor 61, and the motor outputs power to the base block 621 through a coupling, prompting the base block 621, the mounting seat 622, and the cleaning group 63 to rotate in sequence. During the high-speed rotation of the track frame 631 of the cleaning group 63, the centrifugal weight ball 635 at the outermost end of the movable plate 633 will have a movement trend away from the center of rotation due to the centrifugal force. When this centrifugal force is greater than the elastic force of the telescopic spring, it will overcome the resistance of the spring and drive the outer brush plate 634 and the shovel plate 637 to extend outward; The shovel plate 637 adopts a triangular cross-section design. This structure can form an efficient cutting angle during the rotation process. When contacting the garbage in the pipe, the shovel plate 637 can penetrate into the stubborn stains with its sharp edge and completely remove them by mechanical cutting. When the shovel plate 637 completes the removal of the stubborn stains, the brush plate 634 fits tightly to the inner wall of the pipe. The brush plate 634 adopts a special bristle material with good flexibility and cleaning ability. It can brush and clean the residual flexible stains to achieve comprehensive cleaning of the inner wall of the pipe. In addition, the spiral reamer 647 equipped with the device works in coordination with the shovel plate 637 and the brush plate 634 during the movement of the device. The spiral reamer 647 can push the silt and debris in the pipe to the rear of the device through the axial thrust generated by the rotation, further improving the dredging effect. When the dredging operation is completed and the second motor 61 stops running, the movable plate 633, which loses the effect of centrifugal force, automatically drives the shovel plate 637 and the brush plate 634 to retract and reset under the elastic restoring force of the reset spring 632. In terms of maintenance, the cleaning mechanism 6 adopts a modular design concept. The operator can remove the limit cover 644 and the mounting block 624 by twisting the limit screw 646 to disengage it from the limit hole 642. This convenient disassembly method allows the spiral reamer 647, shovel plate 637, brush plate 634 and other wearing parts to be quickly disassembled and cleaned. This design fully considers the maintenance needs during actual use, effectively reduces the maintenance difficulty and maintenance cost of the equipment, and fully demonstrates the humanization and practicality of the device design.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
